Payroll Remittance Deadlines for Ontario Small Businesses: How to Stay on Schedule and Avoid CRA Penalties

If you have employees, payroll is not just about paying wages. You also have to withhold the right amounts, remit them on time, and keep records that can stand up to a CRA review. For many Ontario small businesses, the hard part is not the calculation — it is staying consistent month after month.

What payroll remittances actually cover

Each pay run usually creates a few separate obligations. You withhold income tax, CPP, and EI from employee paycheques, then add the employer portion where required. Those amounts are not business cash you get to keep. They belong to the CRA and need to be set aside until remittance day.

That is why payroll can create stress even when the business is profitable on paper. If remittances are missed or delayed, the CRA can charge interest and penalties quickly.

Know your remitter type

Not every employer remits on the same schedule. The frequency depends on your payroll history and CRA assignment. Some businesses remit monthly, others twice monthly, and larger remitters may have more frequent deadlines. If you are unsure which one applies to you, check your CRA account rather than guessing.

The mistake I see most often is business owners assuming payroll remittances work like regular bill payments. They do not. The deadline is tied to your remitter status, and missing it even once can cause avoidable penalties.

Build a simple payroll calendar

The easiest way to stay on top of payroll is to stop relying on memory. Put the remittance deadline in your accounting calendar, set reminders a few days in advance, and pair it with your payroll processing workflow.

That small routine can prevent the kind of last-minute panic that leads to mistakes.

Do not mix payroll cash with operating cash

One of the biggest payroll errors is using withheld deductions as if they were available working capital. It is tempting when cash is tight, but it creates a future problem you will still have to solve. The safer approach is to move payroll liabilities into a separate reserve account as soon as payroll is run.

That habit makes cash flow easier to understand because the money you actually have is the money you can actually spend.

Common payroll mistakes that trigger problems

Payroll problems are often small at the start. A wrong employee setup, a missed vacation pay calculation, an incorrect CPP or EI deduction, or a remittance that was entered but never submitted can all turn into bigger issues later.

Three mistakes show up repeatedly in small businesses:

  1. Paying workers without a proper payroll setup.
  2. Submitting remittances late because the deadline was not tracked.
  3. Failing to reconcile payroll liabilities against what was actually remitted.

If those issues are caught early, they are manageable. If they sit until year-end, cleanup becomes much harder.

Keep payroll records organized

CRA payroll compliance depends on more than remitting on time. You also need clear records: employee addresses, TD1 forms, pay stubs, source deduction reports, and proof of remittance. If you use accounting software, make sure payroll reports are stored somewhere you can find them later.

Good recordkeeping also helps at year-end when T4 slips and summaries need to be prepared. The cleaner the monthly records, the faster the annual filing process.

What to review every month

A short monthly payroll review is usually enough for most small businesses. Look at these items after each pay cycle:

If the payroll liability balance does not match what you expect, investigate right away. Payroll is one area where small errors compound fast.

When to get help
